Connect Four is one of the most elegant strategy games ever invented. Two players take turns dropping discs into a seven-column grid, and the first to line up four of their own discs \u2014 horizontally, vertically or diagonally \u2014 takes the round. Ten seconds to learn, a lifetime to master.<\/p>\n

This RetroPlayNow version pits you against a built-in AI opponent that thinks several moves ahead. The machine looks for its own winning lines, blocks yours, and favors the center of the board where the best lines are born. It is smart enough to challenge you, but human enough to beat: a solid trap will make it pay.<\/p>\n

A match is a best-of-3 series: the first player to win 2 rounds takes the match. Each round you win scores 200 points, a draw is worth 50, and your final series score is submitted to the RetroPlayNow leaderboard.<\/p>\n

The strategy lives in the details. The center columns control the board: a disc in the middle can become a horizontal, vertical or diagonal line, while the edges can only work in two directions. Set up double threats \u2014 two places where a four-in-a-row is one move away \u2014 and the AI cannot defend both.<\/p>\n

When the series ends, your score converts to Retro Coins at 100 points per coin, so every clever trap you set pays twice: once on the board, once in your arcade wallet.<\/p>\n
